Abstract
A transmission band of an analog signal including successive symbols to be transmitted is notched, where each symbol includes sub-carriers to be modulated. In particular, in each symbol the sub-carriers corresponding to a part of the transmission band to be notched are suppressed. In addition, in each symbol a chosen part of the remaining sub-carriers to be modulated is also suppressed.
